Where did King John finally meet the rebels?

King John finally met the rebels at Runnymede, a meadow by the River Thames, in June 1215. This meeting was significant as it led to the negotiation of the Magna Carta, a charter that aimed to limit the king's powers and establish certain legal rights for the barons and, eventually, all citizens. The location was chosen for its accessibility and neutrality, making it a fitting place for such an important agreement.
